From dc0fe6eee0662e22357e03b7d6cb8260dccd5f72 Mon Sep 17 00:00:00 2001 From: Imran Siddique Date: Tue, 21 Jul 2026 15:34:23 -0700 Subject: [PATCH 1/2] feat(scheduled-agents): agent-integrity for Claude Code scheduled agents New community integration that fingerprints the things that run without you watching -- declared routine specs (schedule, allowed tools, MCP servers, prompt, model) and the auto-run hooks in settings.json -- and warns at SessionStart when any of it drifts from an approved baseline. Drift detection (snapshot/verify/approve + the SessionStart hook) is Python stdlib only, so the hook never blocks a session. /schedule-trace signs a TRACE Trust Record (Level 0, software-only) verifiable by a third party; signing needs agentrust-trace and is exercised in the signing CI job. Mirrors the claude-code plugin layout and its stdlib/signing test split. 21 tests pass; the signed record passes the public Level 0 conformance suite.
